Dancing is one of the ancient means of communication. People of every country have their own national music and dances. In old times people perform special rituals to make bad spirits go away and ask gods for fertile soil, good harvest, health and good weather. So, dancing plays an important role in a culture. Moreover, dancing of a particular country reflects its traditions, customs and history. In the following paragraphs I will give my reasons to support my answer.
First of all, the reason why dancing of a particular country is so unique because many art forms are put together. People need music, costumes, singers to perform, players and of cause dancers. Each of these art forms is unique and singular for every country. In old times people gathered to celebrate or mourn and every occasion had its own music and costumes. For example, ancient tribes painted their faces with ugly and strange patterns, put on colorful clothes and make strange movements around the fireplace.
Second of all, dancing is a combination of body movements that are peculiar for every nation. People of different nations have different bodily movements because dancing is one of the first means of communication. People differently express their feelings such as happiness, sadness, joy and sorrow though movements of their bodies.
To sum up, I think that dancing keeps people's traditions alive through the ages.
